relative import broken?

[Sam]

I also have a problem with relative import; I can't for the life of me
figure out how to use the damn thing. I think the main problem is with
getting Python to recognize the existence of a package. I have

S/
  p.py
  B/
    b.py
  W/
    pyw/
      u.py
      ws.py

and I'd like to get u.py to import all the other 3 programs. I put
empty __init__.py files in all of the above directories (is this
necessary?), and even manually added the pathway (r'C:\Myname\S') to
sys.path, but when I execute

from S import p

in u.py Python gives "ImportError: No module named S". It says "No
module named X" for essentially any package reference, so I think it's
just not recognizing the directories as packages. The docs for
relative import make this sound much easier than it is.

Thanks in advance, I'm at my wit's end.
